Been seeing so many pictures of people bring their dogs to this place called The Green Corridor and I've been very curious about it. Upon further research, it's the old KTM railway track! Looked at the map and... mind blown! It's sooooo long!!!! *faint* So after asking around, people recommended that I take this route from Holland Road to Bukit Timah Railway Station. Actually the map says from Bukit Timah Railway Station to Holland Road, but we did it in the opposite direction based on recommendations. Also, we needed a place to park so we had to start near a residential area.
According to the comments in the map link, there's actually a pretty good map here: Google Maps. It shows you which area has good/okay access points, mud zone and all that. But if you're looking for a photo spot, I'd suggest the one we took because it's the one with the conserved train station and also there's a bridge with tracks over Dunearn Road.
Sooooo, more pictures after the jump!
